Transmission tariffs and service prices

Gasgrid Finland’s price list for transmission tariffs and service prices contains transmission tariffs, the daily imbalance charging method, the capacity overrun charge and the centralised data exchange charges.

In Finland, the postage stamp reference price methodology is applied. In the postage stamp methodology, the distance between entry and exit points or the technical transmission capacity do not affect the unit price of entry or exit capacity; instead, the tariff for entry or exit capacity is the same for all entry or exit points.

Entry capacity reference price 2026

Tariff multipliers for entry capacity products 2026

Tariff multipliers for exit capacity products 2026

The tariffs for short-term capacity products are calculated by multiplying the reference price (the price of an annual capacity product) by the tariff multiplier for short-term capacity products.

Example: The tariff of a monthly capacity product in the exit zone Tariff = (1.31283 × 1.25) €/kWh/day/month = 1.64104 €/kWh/day/month

An illustrative calculation example of the entry and exit capacity tariff unit conversion from a capacity unit (€/kWh/day/year) to an energy unit (€/MWh) is demonstrated at the bottom of the page.

Commodity charge (= energy charge) is paid in the Finnish exit zone

The unit price of the capacity subscription charge is 1730,40 €/MW. The capacity subscription charge is based on the highest peak demand hour of the shipper’s exit zone
portfolio during the year. Shipper shall submit its estimation for the peak demand for next year no later than December 15, or the next business day if December 15 falls on a weekend which shall act as the basis of the monthly invoice during the year. After the year has passed invoices will be settled based on the actual peak demand hour of the year for the shipper.

There is no discount for interruptible capacity at the Inkoo LNG and Hamina LNG entry points and the biogas virtual entry point, because Gasgrid Finland estimates that it will be able to receive, without limitation, LNG and biogas that meet the quality requirements, meaning that only firm capacity is offered.

Also the Finnish exit zone offers only firm capacity.

At the Balticconnector entry and exit point, capacity is allocated implicitly according to the confirmed nominations. Thus, all of the entry and exit capacity offered at Balticconnector is firm capacity.

The price of interruptible capacity at the Imatra entry point is 5 per cent lower than that of equivalent firm capacity products. However, capacity at the Imatra entry point is not available to market participants.

One and a half (1.5) times the unit price based on within-day firm capacity is charged for the quantity exceeding the booked capacity. The capacity overrun charge is thus:
Capacity overrun charge = capacity reference price x 1.5 x price of within-day capacity product

A capacity overrun charge is paid at the Finnish exit zone, the Inkoo LNG entry point and the biogas virtual entry point.
 
Finnish exit zone: If, based on the results of the final balance settleme, the shipper’s exit quantity in the Finnish exit zone exceeds the shipper’s total exit zone capacity of the gas day, the shipper must pay a capacity overrun charge for the gas quantity that exceeds the exit zone capacity allocated to the shipper.
 
Biogas virtual entry point: If, based on the results of the final balance settlement, the shipper’s injection into the gas network at the biogas virtual entry point exceeds the shipper’s total capacity for the gas day at the entry point in question, the shipper must pay a capacity overrun charge for the biogas quantity that exceeds the biogas virtual entry point capacity allocated to the shipper.
 
Inkoo LNG entry point: If, based on the results of the final balance settlement, the shipper’s injection into the Inkoo LNG entry point exceeds the shipper’s total capacity for the gas day at the entry point in question, the shipper must pay a capacity overrun charge for the gas quantity that exceeds the Inkoo LNG entry point capacity allocated to the shipper.

The underutilisation fee is applicable at Balticconnector entry and exit points. The criteria for determining the underutilisation fee and the applicable tolerance are described in the terms and conditions of the Balticconnector capacity allocation mechanism approved by the Finnish Energy Authority.

Tolerance: 10,000–50,000 kWh/h
Pricing: 0.002 €/kWh

The charge is levied from the DSO with regard to the consumption sites in distribution networks owned or operated by the DSO for which information is maintained in the register of the centralised data exchange system (= all daily or non-daily read metering sites in the distribution networks except small-scale individual non-daily read sites using gas only for cooking purposes).

Pricing: 1.56 €/metering site/month

The principles for determining the buy and sell prices of imbalance gas, including neutrality charges, are described in the Terms and Conditions of Balancing, which can be found on Gasgrid’s website legislation and regulation. :

Pricing of connections
As the TSO with system responsibility, Gasgrid Finland has the obligation to connect technically compliant natural gas consumption and storage sites, liquid natural gas (LNG) processing facilities and facilities producing gas from renewable energy sources. The TSO with system responsibility collects from the connecting party all reasonable costs resulting from the connection.

Pricing: The costs resulting from the connection are estimated by Gasgrid Finland on a case-by-case basis.


Nomination imbalance charge
A nomination imbalance charge may be applied in Finnish exit zone.
Pricing: 0 €/kWh 
 
Compensation for non-conformity with gas quality and supply requirements
Compensation terms and conditions are disclosed in the Shipper and Trader Framework Agreement which can be found on our website: Agreements
 
Charges in an emergency situation
Compensation is agreed separately on a case-by-case basis between the transmission system operator with system responsibility and the shipper.
 
Capacity right transfer charge
Pricing: 0 €/transfer notification

Conversion of annual capacity tariff from capacity unit into energy unit (example figures illustrative only)

The shipper estimates that it requires transmission capacity at an average capacity of 100 MW (= total transmission requirement during a gas day is 100 MW x 24 h/gas day = 2,400 MWh/gas day) throughout the year. For this purpose, the shipper books the required entry capacity from the Hamina LNG entry point and the exit capacity for the Finnish exit zone.


The market participant may obtain the transmission capacity from the Hamina LNG entry point at a rate of 1 kWh/gas day for a year for the assumed unit price of the entry capacity. If the annual booking lasts 365 days, the unit price € 0.14277 equates to a transmission quantity of 365 kWh (0.365 MWh). The total transmission quantity required by the shipper is 2,400 MWh/gas day x 365 days = 876,000 MWh. In this case, the shipper requires 876,000 MWh/(0.365 MWh/unit) = 2,400,000 units of entry capacity.

The unit price is 0.14277 €/unit, in other words the total cost is 0.14277 €/unit x 2,400,000 units = € 342,648. The average cost of entry capacity is € 342,648/876,000 MWh = 0.3912 €/MWh.

The shipper may obtain exit capacity for the exit point at a rate of 1 kWh/gas day for a year for the unit price of exit capacity for the Finnish exit zone. If the annual booking lasts 365 days, the unit price € 1.04859 equates to a transmission quantity of 365 kWh (0.365 MWh). The total transmission quantity required by the shipper is 2,400 MWh/day x 365 days = 876,000 MWh.
 In this case, the shipper requires 876,000 MWh/0.365 MWh/unit = 2,400,000 units of exit capacity. This unit price is 1.04859 €/unit, i.e. the total cost is 1.04859 €/unit x 2,400,000 units = € 2,516,616. The average cost of exit capacity is € 2,516,616/876,000 MWh = 2.8728 €/MWh. The total cost of the capacity booking is therefore 0.3912 €/MWh + 2.8728 €/MWh = 3.264 €/MWh.
